which a sheet of material passes through the machine and has only one row of blanks cut out, after which it is removed from the machine and another sheet inserted or the same sheet reinserted into the machine. I

The machine taken as an illustration of the invention is more particularly designed to act upon cardboard or similar material, but is of course susceptible of being used in connection with other sheet material, such as tin, &c. a

The object ofthe invention is to produce a .machine of this character generally improved invits construction, more easily manipulated, and requiring less attention on the part of the operator, and yetwithal perfectly reliable in its operation. In carrying out this object the invention is characterized by the fact that the operation of the feeding mechanism is independent of the punching mechanism. The feeding mechanism operates continuously, while the operation of the punching mechanism is controlled by the absence or presence of a blank in the machine. Hence the punching mechanism is normally at rest, except when released by the presence of a blank at a certain point in the machine, while the feeding mechanism acts continuously irrespective of the presence or absence of a blank and independently of the punching mechanism. After each row of blanks has been cut it is necessary to reinsert thesheet into the machine until the entire sheet has been cut out. In order to use up the material as thoroughly as possible, it is customary to produce a staggered effect in a well-known manner. In the present instance this efl'ect is produced by means of two gages located with reference to. the punch. in such a inanne'r that one gage will be a predetermined number I of blanks away from the said punch, while the other gage is one-half blank farther away from the said punch than the first-mentioned gage. Means are further provided whereby these two gages are raised alternately when inserting a sheet. The position of these gages is adjustable. The operation of the punch is in this instance controlled by what is denominated as a punch releasing member, which when lifted by the blank or sheet as it advances causes the punch to operate. It is advisable that the punch should not be operated except when sufficient material is presented to cut Lil a full-size blank, and this punch-releasing member is therefore so positioned with relation to the punch that it is a distance away from the same somewhat greater than the size of blank to be produced; The position of this punch-releasing member is adjustable, so that its position can be varied to correspond with the amount of scrap left over at the tail end of the sheet and not capable of being formed into a'perfect blank of a size equal to the size the machine happens to be producing at the time. In this way as the punch-releasing member causes the punch to actupon the revolution of the machine next following its release if there is any less material left than a fullsized blank the punch will not operate upon the next succeeding revolution.

In connection with the punch-releasing member there is provided a suitable clutch mechanism and means for moving the clutch into a position. once to every revolution,

where'it is capable of being acted upon by the punch-releasing member, the parts being arranged in such away that unless the said punch-releasing member does act the clutch resumes its inactive position without affecting the punch,

A safety-stop is provided whereby the clutch'can be thrown out at will, thereby stopping the operation of the punch.

In addition to the fo egoing the invention comprises the novel features of construction and combinations of parts, as will more fully hereinafter appear.

In the accompanying drawings a concrete structure has been set forth illustrating the invention, which, however, admits of a wide departure from the construction shown withinvention.

In the said drawings, Fi ure 1 is a front elevation of a machine em bodying the inout overs'tepping the broad boundary of the of the machine, and 2 is the feed-table.

"stance the blank is both out and drawn; but i the invention does not necessarily involve aconstruction having as one of its elements 3'indicates the punching mechanism, in this instance composed of the die 4, blank- In the present in means for both cutting and drawing a blank.

The parts are all operated from the main shaft 7, the blank-holder being operated by means of cams 8 and rollers 9 in the usual Way, while the punch is normally held up by means of the springlO in the tower 11 and is moved down by means of the cam 11*; The

Mounted loosely upon the main shaft 7 is a iiy-wheel 12, constituting. a main driving member adapted to be throwninto and out of connection with v the shaft or operating means 7 for the punch, in the mannerhereinafter more fully setforth. I

. 13 indicates the sheet-feeding mechanism,

Whose operating means (set forth in detail later on) are operated continuously from thesaid driving member.

On one side of the machine 'there are' two sets of feeding-rolls 14, each set consisting of two superposed rolls 15, 16, 17, and 18, all

located on one side (the feeding end) of the punch mechanism. On the other side of the punch mechanism there are three sets of rolls-viz. the guiding-rolls 23, the shearing rolls 24, and the scrap-conveying rolls 25. v

The driving means for the feeding mechanism are constructed as follows: Located in the rear of the machine is a counter-shaft 26, which is driven intermittently in one direction only, but continuously so, from the driving member 12 by the following means: Moving with the fly-wheel 12 is a crank 27, having the rack 28 meshing with the gear 29,

mounted loosely on the shaft 26 or elsewhere.

Moving with this rack'28 is a pawl 30, engag-.

ing with the ratchet 31 on the said countershaft 26. i

The various feeding-rolls are mounted on transverse shafts 32, 33, 34, 35, 36, and 37,

' receiving their motion from th e counter-shaft 26 by means ofbevel-gears 38. The upper and lower shafts which carry the feeding- "rolls are geared together by meansof spur- .gears 39 in a well-known manner. i.

w 40 and 41 indicate the two gages, consisting'ofslidlng blocks 42, adjustable in the way in sliding boxes 58.

43 of the feed-table 2 and secured in position by means of screws 44. The sliding blocks 42 carry the gages 40 and 41, which are in the form of pins, normally helddown by means I of springs 45.

Means are provided for raising v'these ages alternately. A simple expedient for doing this consists in the earns 46 and 47, which are so arranged thata high oint or tooth 48 is always in alinement wit onegage, while a: notch 49 is always opposite the other gage.

These two cams are rotatably mounted on the stud 50, carrying the ratchet 51, with tached to the foot-treadle 54 or other device by means of the link 55-and'rod' 56, so that by lifting one of the said gages. It follows that when the foot-'treadle is depressed to insert another sheet the ratchet will again be turned-and the other gage lifted. v

- In order to properlyinse'rt the sheet, the upper'rell 16 of the first 'set of feeding-rolls foregoing part of the machine is well known. -I has to be "lifted. This is accom' lished" by pivoting the shaft 33, carrying-sai rolls at 57 at its rear end, and mounting the saidshaft 33 The shaft is normally held down by means of the s' ring 59 and is raised, preferably, by means 0 the'same foottreadle which moves the gages in position.

In the structure shown the lever 60, pivoted .at '61, is connected to the link 55, and acts when thetreadle is depressed to lift the said t a -w It is important 'that't'he-feed-rolls 16 and 18 should not be lowered when pressure is released on the fo'ot-treadle,.as this might'occur on the upstroke'of'therack 28, which is the stroke that imparts motion-to the,jshaft 26 and conse uently to the, feeding arolls: If this were one, the reed-r0113 would hayerotated' partlybefore; acting on the sheet' and would therefore act im roperly on the said sheet, not imparting a ll movement tothe same. This would of course throw the sheet out of register with the punching mechanism.

Provision is therefore made to lock the shaft 33 in its elevated position and for moving-it down positively when the rolls are in a state of rest. This is accomplished by providing a rod 62 on the sliding box 58, having the head 63, and by providing aslockingcain64,' which moves automatically inunder the said head by reason of the spring 65, which turns the said cam 64 an'dthe rock-shaft 66, on

-whieh it is mounted. The downst' ke of the rack 28, which imparts no motion to the feeding mechanism, is' utilized to release this I which engages the pawl 52. The stud 50 is "mounted on the pivoted forked lever 53, at- 8o depressingthe said foottreadle'the cams are lifted, turningthe ratchet 51 one tooth and locking-cam by means of the collar 67 on the saidrack, engaging with the loose sleeve 68,.

the link 69 or otherwise.

The main driving member in thisinstance connected to the rock-shaft 66.by means of the fly-wheel 12-'and the operating means for the unching mechanism-1n this instance the sha t 7-are thrown in and out of connection at certain periods by means of the clutch mechanism 70. The clutch mechanism cononly free; to follow'this tendency whenthe bell-crank is moved out of the way by means .of the cam 77 acting on the roll 78, connected,

. to the said bell-crank. The parts are so arranged, however, that when the cam 77. acts to'move the stop out of the Way the two grooves72 and 74 are not in alinement with each other,' so;that no result follows. Means,

however, are provided whereby the stop will be locked so as to prevent its return, and thereby causin the parts to be thrown into clutch with eac other when the two grooves coincide. These means willpreferably-take the following form: The roll 78, which is connected to the bell-crank or stop .7 6, is provided with a sliding member 79, moving in the bracketSO. The roll 78 is normally held up against, the cam 77011 the fly-wheel 12 by means of the spring 81, and the sliding member- 79 is provided with a notch 82, with which the latch 83 is adapted to engage to hold the roll 78 down in the position to which it has been moved by the cam 77, and thereby holding the stop .7 6 out of the way of the tail of the key. This latch 83 is mounted on the. rock-shaft 84 and is adapted to be moved positively at certain periods. The means controlling this latch is the punch-releasing member 85, conveniently pivoted on the shaft 33 and made in two parts 86 and 87, one of which is slotted, connected by means of the set-screws 88, so-that the length of the member can be adjusted. The free end of this dog rests on the feed-table and is adapted to be raised by the blank or sheet when moved in under the same by the feed-rolls. This slight motion is transmitted through the connection 89 to the link 90, attached to the latch 83. in this eonnectiqn 89 there is a cylinder 91,'in which is located the spring 92, adapted to be com ressed by the plunger 93, so that if the blan lifts the punch-releasing member at a time when the cam 77 has not yet moved the sliding member 79 down so as to allow the movement of the connection to turn the latch into the notch power will be stored in this spring. When the cam 77 does move the sliding member down, registerin the notch 82 with the latch 83-, the latter wil be forced into the said notch by the action of the said s ring." \Vhen the blank or sheet has passe away from under the punch-releasing member, the latter will drop, eausin the'latch to be moved out of the notch an: moving the step into the path of the tail of the key, thereby throwing the clutch out.

In addition to the foregoing there is pro vided a safetystop in the form of a foottreadle 94, connecting by means of the rod 95 with the link 90, whereby the latch can be thrown out at will and independently of the punch-releasing dog.

The operation of the machir is as follows: Assuming that the main driving member or fly-wheel 12 is running continuously, the foot-treadle 54 is depressed, thereby lifting the shaft 33 and turning the cams 46 and 47 and lifting one of the gages 40 and 41. The

sheet is now inserted, being registered against one of the said gages, which is a predetermined number of blanks away from the punching mechanism. The foot-treadle is now released, and upon the next succeeding downstroke of the rack 28 the shaft 33 is moved down'and the sheet clamped between the feed-rolls 15 and 16. Upon the continued operation of the driving means for the feeding mechanism the sheet will advance step by step,,gui ded alongthe ledge 96 until it lifts the punch-releasing member 85," whereby motion is imparted to the latch 83, thereby causing the latter to move into the notch 82 of the sliding member 79, which latoccupy both grooves, and hence motion will be imparted to the main shaft 7 from the fly wheel 12, thereby actuating the punching ter, it is assumed, has been previously moved mechanlsm on the next revolution of the main shaft.

and upon the two grooves 72 and 74 being rnove the latch. 83 into the notch 82, thus holding the stop out of the'patli of the key of the clutch. Should diilic'ulty beexperieneed with the machine, the safety-stop'can be op- If the cam 77 has not moved, the step out of the way and the member 7 9.,

' down, power will be stored in the spring-92,1

erated and the punching mechanism be stopped. The punch-releasing .member is adjusted to suit the amount of scrap left over and is located, say, one blank and one-seventh away from the punching mechanism. It is obvious that so long as there is material left to hold the punch-releasing member. in its raised position, the operation of the punching mechanism will continue. 'VVhen, however, but one blank and one-seventh of a blank are left, the member will move down after the last full blank has been fed underthe punching mechanism and after the next succeeding stroke of the punch the clutch will be thrown out and the punehingicease.
